Hello All,
In two different books, Simple Data Binding to a control is explained
with an example of a TextBox where the data is initialized with an
array.
For example a class is defined as such:

Hello,
I'm trying to use an ArrayList to do data binding, but am getting an
error I don't understand. I posted this in another thread, but that was
all confused with various other problems, which could be why no-one
answered it!! I've now narrowed the problem down, so am starting a new,
more specific, thread. Sorry it's a bit long, but it's reasonably simple
stuff.

Hi,
I've noticed a bug in VB.NET (latest .NET Framework)...
- I have a TabControl on a form with several tabs.
- Each tab contains text boxes that are bound to fields in a data source
(DataBindings).
- When I display a record and then try to access the .Text property of one
of the text boxes on any tab except the current tab, the result is an Empty
string.

I am not sure how many are aware of this sort of data binding,
but as it is new to many (classic) VB developers I thought I
would post this once just to let people know of its availablility.
There are cases where properties of one object is dependant on
a property of another object. For a common example, when you
bind an ArrayList to a ComboBox using the combo's DataSource
property, the combo box fills up with items from the array list....

The following block of code defines a FormView control "FormView1" with
an EditItemTemplate which has a Label and a TextBox control within it.
While the Label "RequestIDLabel1" has one-way data-binding to the
underlying column "RequestID", the TextBox "RequestDateTextBox" has
two-way data-binding to the underlying column.
If I were to generate the EditItemTemplate dynamically at runtime, and
add the Label and TextBox controls at...

Hi,
I have an ASP.NET page with a ListBox that is data bound to a table
with a single field (it holds a list of valid IDs). The page also has
a textBox into which you can add new valid IDs, one per line (this is
in order to make the process of adding new IDs easy, since it's only
done at time of configuration).
I have no problem with retrieving the contents of the textBox,
splitting it into a string array, validating the individual...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
